Method and Apparatus for Data Transmission, User Equipment and Base Station

1. A method of data transmission, comprising: receiving two transmissions of service data sent by a base station; receiving scheduling information indicating a transmission resource location of first service data which is preempted by second service data in a former transmission of the two transmissions of the first service data and the first service data corresponding to the transmission resource location, carried in scheduling control data on a latter transmission of the two transmissions of the first service data; receiving the first service data corresponding to the transmission resource location according to the scheduling information; sending Hybrid Automatic Repeat reQuest (HARQ) feedback information associated with the first service data corresponding to the transmission resource location and the HARQ feedback information associated with service data other than the first service data of the transmission through which the first service data are transmitted to the base station simultaneously or separately, thereby sending the HARQ feedback information to the base station in multiple ways; and upon that there are service data for which a transmission resource is preempted and the transmission of the service data are sent to user equipment (UE), receiving the service data for which the transmission resource is preempted according to the scheduling information carried in the scheduling control data on the transmission of the service data, thereby realizing multiple ways of determining that there are the service data for which the transmission resource is preempted in multiple ways.

2. A communication system implementing the method according to claim 1 , comprising the UE, wherein the UE is configured to implement operations of the method.

3. The communication system according to claim 2 , further comprising the base station, wherein the base station is configured to: send one transmission of the first service data to the UE, to facilitate the UE receiving the first service data corresponding to the transmission resource location according to the received scheduling control data, where the scheduling control data on the transmission of the first service data carries scheduling information indicating a transmission resource location of the first service data which is preempted by the second service data and the first service data corresponding to the transmission resource location, the first service data corresponding to the transmission resource location are the service data for which the transmission resource is preempted; and send another transmission of the second service data the UE, to facilitate the UE receiving the first service data corresponding to the transmission resource location according to the scheduling control data, where the scheduling control data on the transmission of the second service data carries the scheduling information indicating a transmission resource location of the first service data which is preempted by the second service data and the first service data corresponding to the transmission resource location.

4. The communication system according to claim 3 , wherein the base station is further configured to: send two transmissions of the first service data to the UE, to facilitate the UE receiving the first service data corresponding to the transmission resource location according to the scheduling control data on the latter transmission of the two transmissions of the first service data, where the scheduling control data carry the scheduling information indicating a transmission resource location of the first service data which is preempted by the second service data in the former transmission of the two transmissions of the first service data and the first service data corresponding to the transmission resource location; receive HARQ feedback information associated with the first service data corresponding to the transmission resource location and HARQ feedback information associated with service data other than the first service data of the transmission through which the first service data are transmitted, sent simultaneously or separately by the UE; and determine first service data which are failed to be sent according to the HARQ feedback information, so as to provide a condition for re-transmitting the first service data which are failed to be sent.

5. A method of data transmission, comprising: determining that there are service data for which a transmission resource is preempted; sending two transmissions of the service data to User Equipment (UE); sending, to the UE, scheduling information indicating a transmission resource location of first service data which is preempted by second service data in a former transmission of the two transmissions of the first service data and the first service data corresponding to the transmission resource location, carried in scheduling control data on a latter transmission of the two transmissions of the first service data; sending the first service data corresponding to the transmission resource location according to the scheduling information; receiving, from the UE, Hybrid Automatic Repeat reQuest (HARQ) feedback information associated with the first service data corresponding to the transmission resource location and the HARQ feedback information associated with service data other than the first service data of the transmission through which the first service data are transmitted to the base station simultaneously or separately, thereby receiving the HARQ feedback information to the base station in multiple ways; and upon that there are service data for which a transmission resource is preempted, sending the transmission of the service data the UE, such that the UE receives the service data for which the transmission resource is preempted according to the scheduling information carried in the scheduling control data on the transmission of the service data, thereby realizing multiple ways of determining that there are the service data for which the transmission resource is preempted in multiple ways.

6. The method according to claim 5 , wherein the determining that there are the service data for which the transmission resource is preempted comprises: judging that second service data preempts a transmission resource for first service data; or detecting that the second service data preempts the transmission resource for the first service data.

7. User equipment (UE), comprising: a processor; and a memory for storing instructions executable by the processor, wherein the processor is configured to implement operations including: receiving two transmissions of service data sent by a base station; receiving scheduling information indicating a transmission resource location of first service data which is preempted by second service data in a former transmission of the two transmissions of the first service data and the first service data corresponding to the transmission resource location, carried in scheduling control data on a latter transmission of the two transmissions of the first service data; receiving the first service data corresponding to the transmission resource location according to the scheduling information; sending Hybrid Automatic Repeat reQuest (HARQ) feedback information associated with the first service data corresponding to the transmission resource location and the HARQ feedback information associated with service data other than the first service data of the transmission through which the first service data are transmitted to the base station simultaneously or separately, thereby sending the HARQ feedback information to the base station in multiple ways; and upon that there are service data for which a transmission resource is preempted and the transmission of the service data is sent to the UE, receiving the service data for which the transmission resource is preempted according to the scheduling information carried in the scheduling control data on the transmission of the service data, thereby realizing multiple ways of determining that there are the service data for which the transmission resource is preempted in multiple ways.
